Optimization and Mechanical Properties of Fabricated 2D Wood Pyramid Lattice Sandwich Structure

In order to obtain a lightweight, high strength, and large design space wooden sandwich structure meet the needs of modern buildings, mechanical properties fabricated 2D pyramid lattice were studied. this paper, compressive specimens with different arrangement Lattice Sandwich unit cells are The upper lower panels core materials made into single cell by inserting glue, prefabricated truss is prepared mortise tenon splicing method. results show that in specimen has significant effect on bearing capacity, energy absorption, failure mode specimen, flat compression performance panel-reinforced better than unreinforced veneer. finite element analysis consistent test results. main modes fracture panel cracking. These provide theoretical basis for system wood-based future.
